Opus Energy 2022: Plans, Prices and Reviews


Initially founded in 2002 as ‘Oxford Power Holdings Limited’, Opus Energy is an busineess energy supplier that is owned by the Drax Group, a British company that generates electricity with a focus on a carbon neutral future.
With its headquarters based in Northampton, Opus gains its electricity from renewable energy sources such as wind, solar, hydro and anaerobic generators and, unlike most UK energy suppliers, only provides its energy to business customers, rather than households.
Having grown substantially in size over the last twenty-or-so years, Opus Business Energy now supplies almost 370,000 UK businesses with their energy; this is equivalent to 1.5% of all UK energy consumption.
On this page, we’re going to take a look at Opus Business Energy in full, uncovering their customer reviews, energy plans and prices.

Who is Opus Energy?

Opus Energy is a UK energy supplier who supplies gas and electricity to businesses in the UK. With all their operations online, they primarily work with small and medium sized businesses (SMEs) as well as the retail industry and housing associations; priding themselves on their commitment to 100% renewable energy sources.

They were initially founded with the goal of being innovators within the energy market and, as a result, they’ve created an online-only business that makes it simple to monitor and manage energy usage online. This not only creates cost savings that can be passed on to their customers, but it also allows them to reduce the impact of their own business on the environment, supporting their mission towards sustainability. Opus’ current goal is to become carbon negative by 2030, and are the world’s first energy company to commit to this – with many aiming for ‘carbon neutrality’, rather than a negative carbon impact within the next decade.

While they’ve not yet broken into ‘big six’ territory, they are now one of the largest independent energy providers in the UK, responsible for 1.5% of UK energy consumption. Some of their more well-known business clients include the high-street retailer White Stuff and broadband and TV providers, Virgin Media.

Who owns Opus Energy?

Drax Developments Limited, an arm of the Drax Group, owns Opus Energy having bought the company in February 2017. Originally, Opus was founded and owned by Charlie Crossley Cooke, who served as the Managing Director for 15 years, before resigning from his positions as Director accompanying the sale of the company in 2017.

How many customers does Opus Energy have?

Opus reports that they currently ‘energise’ over 368,000 business premises with their 100% renewable electricity and energy services.

Is Opus Energy any good?

Although their customer feedback is mixed (we’ll come on to that shortly!), there are a range of perks for Opus Energy customers, including:

  • 100% renewable energy
  • Experienced business energy account managers
  • All accounts are managed online under the ‘My Opus Energy’ portal
  • A mixture of fixed-fee and variable tariffs
  • Free smart meter installations, even if you move premises.

However, Opus does have some drawbacks. Some of their weak spots are:

  • Only supplies energy to businesses
  • Frequently poor public customer feedback
  • Issues with overestimating bills for non-metered customers.

Opus Energy customer reviews

As a business energy supplier, Opus Energy isn’t eligible to take part in the annual Which? Energy Survey or other common energy awards that ask consumers for feedback on their experiences with their suppliers.

However, we can look at their Trustpilot page to find some Opus Energy reviews!

With an overall review score of 2.1 from 1,333 customer reviews, Opus are marked as ‘Poor’ based on their customer feedback to date. Out of all the 68 UK energy suppliers on Trustpilot, Opus Energy comes in position 67 in rank.

Trustpilot stats show that 68% of their ratings are bad, and 3% poor, with the majority of their reviews coming organically rather than by invitation. However, they do reply to negative reviews within 24 hours and have replied to 93% of their negative reviews, showing a commitment to dispute resolution and listening to customer feedback.

Their positive reviews mention…

  • Great customer service by staff members
  • Competitive rates and pricing
  • Renewable energy tariffs.

While their negative reviews frequently include…

  • Issues with the billing and customer service responses
  • Long wait times to speak to someone on the phone, up to 30 minutes or with calls going completely unanswered
  • Difficulties with the switchover process, both when joining Opus and when leaving
  • Reports of estimates being used to generate bills, even with smart meters installed.

Opus Energy pricing

Is Opus Energy cheap?

Opus Energy deals directly with customers for their pricing, so it’s not simple to tell how competitive their pricing is. However, with Switch-plan, we can help you compare prices and find the best tariffs for you and your business. Give us a call on 0330 818 6223 to get started.

Do Opus Energy do business energy tariffs?

Yes, since their inception, Opus Energy exclusively provides energy to businesses rather than residential customers. As a result, all of their tariffs and rates are applicable for businesses only. Opus works with some big UK brands such as White Stuff, a large high-street retailer and Virgin Media, who provide broadband, TV, phone and mobile services to customers in the UK.

Switching your business energy to Opus

Here at Switch Plan, we only deal with residential energy switching at the moment. But this may change in the future, so keep your eyes peeled! In the meantime, we’d be delighted to support you with your residential energy. To get started with your home energy, give us a call on 0330 818 6223.

Opus Energy Tariffs

While Opus Energy tariffs aren’t published on their website (as they deal directly with business customers), we do have some insight on their two main tariffs: Opus Advance and Opus Advance Plus.

The Opus Advance tariff is the standard, and includes:

  • Energy supplied by renewable generators in the UK and Europe
  • A reduction in carbon dioxide, by choosing renewable power
  • Digital certificates, social icons and buttons to showcase your sustainability as a business
  • A range of partner perks from reductions in business insurance costs to 50% off lights and smart controls
  • Certifiable energy.

There is also an Opus Advance Plus tariff, which is similar to the standard package, but also includes:

  • The option to support their 2,300 British generators, for a premium.

Opus Energy fuel mix

Opus Energy’s latest report covering electricity supplied between April 2019 – March 2020 showed a very simple breakdown of their energy breakdown: 100% renewables.

Of their renewable energy resources, the breakdown is as follows:

  1. 48% from wind power
  2. 24% from solar energy sources
  3. 16% from bioenergy
  4. The final 9% from hydro.

What other products & services does Opus Energy provide?

As well as selling energy to business customers, Opus Energy also buys energy. Under the two schemes devised by the Department for Business, Energy and Industrial Strategy (BEIS), you will be paid for your contribution to cutting carbon emissions by generating renewable energy. Via Opus, you can sell your energy to the Grid who promise quick payments, and they’re currently particularly keen on renewable energy from wind, hydro, solar and anaerobic digestion methods.

Smaller energy generators will be eligible for Feed-In tariffs (rewarded for every MWh you create) where the rate is set every three months or so by Ofgem.

For bigger suppliers, they can sell energy via Renewable Obligation Certificates (ROCs) which don’t have a standing rate, but are charged at the current market rate for energy.
